Figure 6.

Alignment of RTM2 N-Terminal Sequence, α-Crystallin Domains of Plant Small HSPs, and the N-Terminal Region of Arabidopsis Atuk.

Gaps in the alignment are indicated by dashes. The α-crystallin domains are located between the arrowheads. Positions occupied by at least nine structurally conserved or identical residues are highlighted in gray or black, respectively. Representatives from each of the five major small HSP classes (cytosolic classes I and II, endomembrane [Endo], chloroplast [Chl], and mitochondrial [Mito]) from Arabidopsis (At), pea (Ps), and soybean (Gm) are shown. GenBank accession numbers are as follows: Atuk, AC005623; AtClassI, CAA35182.1; PsClassI, P19243; GmClassI, P05478; AtClassII, P29830; PsClassII, P19242; GmClassII, P05477; AtEndo, AAA19931.1; PsEndo, P19244; GmEndo, P30236; AtChl, AAA32818; PsChl, P09886; GmChl, P09887; AtMito, AAB38795; PsMito, P46254; and GmMito, Q39818.
